Struct std::io::error::repr_bitpacked::Repr

#[repr(transparent)]
pub(super) struct Repr(NonNull<()>, PhantomData<ErrorData<Box<Custom>>>);

The internal representation.

See the module docs for more, this is just a way to hack in a check that we indeed are not unwind-safe.

fn is_unwind_safe<T: core::panic::UnwindSafe>() {}
is_unwind_safe::<std::io::Error>();
